LOOSE-LEAF BINDER. 5

Application filed September 14, 1921. Serial No. 500,520.

To allwhomt may concern: 1

Be it known that I, Lnaor L. PoN'r1Us, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Loose-Leaf Binders, of which i the following is a specification.

Thisinvention relates to loose-leaf binders. It will be explained as applied to a binder in book form for holding a plurality of relatively short overlapping leaves in such position that the upper margin of each leaf may be visible. p

In account and other record books and files it is often necessary to insert additional leaves between existing alphabetically, numerically or otherwise arranged leaves and maintain fixed upper or lower marginsso that headings on. all of the leaves may be visible for ready reference. Ordinarily the necessary shifting of the leaves in front of or behind the points of insertion requires considerable time'and labor and offers many opportunities for mistake.

One of the objects of this invention is to provide an improved looseeleaf binder.

Another object is to provide a binder wherein insertions .ofleaves may be made with a minimum of labor, time and opportunity for mistake. v

. Another object is to provide a binder which may be used with records kept other desired form. v

Another object is to provide a binder which in book or dispenses with hinges.

Another object is to provide a binder which is simple, reliable, easy to manipulate and inexpensive to manufacture.

Other objects .and advantages after appear, a t p Embodiments of the invention are illustrated in the accompanying drawings, in which' Fig. 1 is an enlarged broken top plan of one form of binder.

Fig. 2 is an end elevation of the binder in closed or leaf-holding position. v

will herein- Fig. 6 is a portion of the same leaves with i another leaf inserted between them.

Fig. 7 shows a binder with a modified form of leaf-holder, and

Fig. 8 shows an end'elevation of a modified structure.

Figs. 1 to 6 will first be described. 7

The binder. has two leaf-holder supports 10 and 11 adapted to slide upon each other, as will be hereinafter described. These supports may be made of any suitable material such as sheet steel. Support 10 carries a series of male leaf-holders 12 to 22 and support 11 carries a corresponding series of female leaf-holders 23 to 33, inclusive. Support 10 has an upstanding flange 35 to which a holder bar 36 is rigidly secured in any appropriate manner such as soldering,'welding or riveting. Bar 36 has leaf-holders 12 to 22 secured thereto by any suitable means. Support 11 has an upstanding flange 37 which carries a holder bar 38 to which female leaf-holders 23 to 33 are secured. The

spacingof holders 12 to 22 and 23 vto 33 are uniformly the same so that they will'register I orpins 41 are anchored in fixed'positions in support 11 and extend through U-shaped ,slots 42 in support 10. This pin and slot connection permits supportlO to be freely moved both laterally and longitudinally relative to support 11. V V I I The length of the parallel legs of slots 42 are such that the male leaf-holders maybe completely withdrawn fromthe female leafholders and separated therefrom to permit the ready application of leaves. The length of the interconnecting base of slot 42 is such that support 10 may be moved longitudinally of support 11 a distance corresponding to the spacing of the holders. 1

A back 43, to which front and rear covers 44 and 45 are hinged, may be secured to the curved back plate 40 of support 1 1 in any.

appropriate manner. I v

r The leaves used with binders of this char-' acter will ordinarily have a series of holes therein for fitting on the binder leaf-holders.

Usually the leaves are short relative to the length of the binder and each has a margin at the topor bottom for receiving indicating data, such as customers names, etc. The depth of the margin is substantially equal to the spacing between the leaf-holders.

In Fig. 5 a portion of two adjacent leaves and 52 are shown in the relation they will assume when bound together in the binder. Assuming that a leaf 51 is to beinserted between leaves 50 and 52, providing the same margins therebetween and maintaining the same margins and relative positions of leaves throughout the hinder, the operation is substantially as follows: I V

The operator divides the leaves of the binder at the point of the desired insertion intotwo groups. As/viewed in the drawings,'the leaves from the upper end of the binder down to the point of insertion form the right-hand group and the leaves from the point of insertion toward the bottom edge, of the binder form the left-hand group.

After the leaveshave beenthus divided into groups the binder is opened by sliding support 10 to the left until the male leaf-holders are completely withdrawn from the female leaf-holders. The left hand groupof leaves are carried over with the male holders while the righthand group of leaves is held on the female holders.

Support 10, carrying the left-hand group of leaves, 'is then slid downwardly upon support 11 the full length of the intercoir necting base of slot 42 to the position shown by the dotted lines of Fig. 1. The two groups of leaves are now longitudinally separated twice the amount of the original separation but the leaves of each group are in the same relative positions. The operator now inserts leaf 51 upon the top of leaf '50, which is the top leaf of the right hand group, placing the same upon the female holders so that the usual margin is left at the top of leaf 50. The binder is next closed and, because of the shift of support 10, the male leaf holders enter the next lower female-holders. Theleaves are now reassembled with the inserted leaf in the desired positionand all of the margins uniformly the same. 7

To return the binder to its original condition the operator again opens'the binder holding all of the leaves on the female hold- When the binder is open support 10 is shifted upwardly to its original position and the binder is again closed whereupon it is in condition for operation to make another insertion. V

Fig. 7 shows a modified form of binder wherein the female form of leaf-holder is dispensed with. 'In this form of binder the ments of one section in the same plane.

leatholders of both sets are alike. The binder has the two slidably related supports 55 and 56 as before. Each plate has a series of similar leaf-holders '57 and 58, respectively. One holder from each support forms a pair, the spacing of which is equal to the longitudinal movement of support 55 relative to support 56. The spacing between pairs is made greater, such as twice the distance between the holders of each pair. Supports 55 and 56 may be provided with small depressions or cups 59 and 60 for receiving the ends of the holders on the other support. Supports 55 and 56 are slidably fastened together by rivets 61 which are secured to support 56 and pass through U- shaped slots in support 55. Thisv form of binder is operated in the manner previously set'forth and functions in the same manner.

Fig. 8 shows a binder wliereiirthecovers are hinged to the leaf-holder supports, the

supports together forming the back of the cover. The binder has two leaf-holder supports 65 and 66 which are slidably fastened together by rivets 67 as previously de scribed. The supports are so formed that when fitted together and closed they provide a back of the desired curvature. Support 65 carries a series of male leaf-holders 68 and support 66 carries a corresponding I The relative shifting of the binder sec tions or leaf-holder supports is accomplished by two angularly related 1nove of the necessary movements to shift and assemble the leaves are shdlng movements so that hinged connections between sections are dispensed with. Insertions may be made at any point and the propermargins obtained and maintained with a minimum of time, laborand opportunity for mistake.

Having described my invention what I, claim as new and desire to secureby Letters Patent, is

1. A loose-leaf binder having two leafholder supports slidably fastened together and slidable relative to each other in two angularly related directions, and a set of leaf-holders carried by each support.

2. A loose-leaf binder having two leafholders supports, means for slidably fastening the supports together and permitting relative transverse and longitudinal movement therebetween, and a set of leafholders carried by each support. 7

3. A loose-leaf binder having two leafholder supports one being mounted for movement in one. plane both transversely and longitudinally relative to the other, and a series of leaf-holders mounted on each support.

4. A loose-leaf binder having two leaf supports interconnected by a pin and slot connection whereby one support may be slidably moved relative to the other in two angularly related directions, and-a series of leaf-holders on each support.

5. A loose-leaf binder having two leaf supports one of which is provided with 'a substantially U-shaped slot, a pin slidably fitting within the slot and securing the two supports slidably together so that one support may be moved both transversely and longitudinally of the other support, and a set of leaf-holders carried by each support.

6. A loose-leaf binder comprising two supports, a set of male leaf-holders projecting from one support, a corresponding set of female leaf-holders projecting from the other support, and a sliding connection between the supports so that corresponding male and female leaf-holders may be brought into register and telescopically fitted together and one support may be longitudinally moved relative to the other support to bring the male leaf-holders into register and telescopic relation with adjacent female leaf-holders.
